I wonder if we were at Edmonds at the same time? A friend and I went up there to dive, but discovered the backup regulator on her set was leaking and I couldn't make it stop, so we just sat and chatted for a while, and eventually left about 10:30 or 11.
I don't know what to tell you about the latches. I've had my primary light for almost ten years and somewhere in the neighborhood of 1200 dives, and I have yet to have a latch come undone. My husband has had it happen once. So that's about 2500 dives or so. It does seem to me that I have seen people use a strip of inner tube and stretch it over the latches as both insurance from opening and also to prevent line from catching in the clips. I haven't felt the need, but I might change my tune if I lost a $300 battery due to having a latch come open.
